What is a non-conjugate ketone and what is a conjugate ketone?

Answer 1

Conjugated ketone has a C=C unit attached directly to carbon of the carbonyl group. While in Non conjugated ketons the carbonyl group don't contact with any C=C unit

#CH_2=CH-C(O)-CH_3# is a simple conjugate ketone (the C atom connected to the C atom of the carbonyl group forms a double bond to another C atom.while# CH_2=CH-CH_2-C(O)-CH_3 #would be non-conjugate because the C atoms forming the double bond don't contact the carbonyl group directly.

A non-conjugate ketone is a ketone in which the carbonyl group is not part of a conjugated system of double bonds. A conjugate ketone is a ketone that is part of a conjugated system of double bonds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
